Document Summary

Variable cost: a cost that increases in total with an increase in activity and decreases in total with a decrease in activity. Mixed costs: costs that have both a xed and a variable component, total cost = total xed costs + total variable costs. Step costs: displays a constant cost for a range of output, then jumps to a new cost level for a different range. Creating and using a cost formula: de ne the cost formula. Identify the independent variable: dependent variable - a variable whose value depends on the value of another variable; total cost, independent variable - a variable that measures output and explains changes in the cost. Intersect and slope: intersect - the point at which the cost line intercepts the cost axis; aka xed cost, slope - corresponds to variable rate (variable cost per unit of output) Variable rate = high point cost - low point cost.

Fixed costs are costs that remain the same in total dollaramount as the activity base changes. TRUE ORFalse

A relevant range is the range of activity over which the changesin the cost are of no interest. True orFalse

The break-even point is the level of operations at which thecompany has neither a loss nor a profit. True orFalse

As fixed costs increases, the break-even point increases.True or False

FIFO method refers to the fact that the first items in are thelast items out. True or False

Mixed costs are costs that have characteristics of both avariable and fixed costs. True orFalse

An example of an activity base is units produced.True or False

As the unit selling price increases, the break-even pointincreases. True or False

The difference between contribution margin and operatingleverage is fixed charges. True orFalse
